I am looking at purchasing a Kohler Cimarron and am going to purchase either the 3589 or the 3609. I have to buy one of these because of various reasons (color etc). It appears that the only difference is that the 3589 is 1.6 gpf and the 3609 is 1.28 gpf.
In looking at reviews, the 3589 was ranked considerably higher than the 3609 by Consumer Reports mainly because they reported the 3609 was not quite as good at solid waste. Consumer Reports report, however, was done in January of 2009 and may have been based off of the class six flush. Is class six inferior to class five and that is why it was discontinued?
To confust things a bit more, reviewers ranked the 3609 five stars versus four stars for the 3589, again I suspect some of those reviews were based off of the class six for both. It still doesn't make sense though that a 1.28 would be ranked better than a 1.6.
The Home Depot reviews have both about the same.
Common sense would tell me that, all else equal, the 3589 would flush better than the 3609 because of the extra water. Am I missing something?
